Abstract

The invention relates to an evaporator, especially to an external circulating evaporator. The external circulating evaporator comprises a heating chamber and an evaporating chamber which are connected with each other through a circulating pipe. The heating chamber is respectively provided with a steam inlet, a feed liquid inlet and a condensed water outlet. The evaporating chamber is respectively provided with a secondary steam outlet and a concentrate outlet. The secondary steam outlet is connected with a recovery device. According to the external circulating evaporator, recirculation evaporation of the feed liquid can be realized by connecting the recovery device at the secondary steam outlet, thus effectively reducing waste of the feed liquid.

Description

technical field [0001] The invention relates to an evaporator, in particular to an external circulation evaporator. Background technique [0002] The external circulation evaporator is suitable for the evaporation and concentration process of liquid materials in pharmaceutical, food, chemical, light industry and other industries. At present, the external circulation evaporator manufactured in the domestic market is generally composed of a heating chamber, an evaporation chamber and a circulation pipe. The secondary steam generated in the end is discharged out of the room through the secondary steam outlet of the evaporation chamber, and the concentrated liquid returns to the lower part of the heating chamber along the circulation pipe for recirculation and evaporation. When the specified concentration is reached, the material starts to be discharged continuously. At the same time, the feed is also continuous. During this process, when the secondary steam is discharged thro...
